Description

Technical Field

[0001] This application relates to the field of injection molding production, and in particular to a sprue cutting device. Background Technology

[0002] In the mass production of plastic products, injection molding dominates due to its high efficiency and ability to mold complex shapes. After injection molding, the parts are cooled and solidified, but the parts connecting the injection molded part to the runner and the excess material on the product need to be removed. These waste parts that need to be removed are collectively referred to as sprues. In related technologies, the sprue removal process involves operators removing the injection molded part containing the sprue from the injection molding machine. Using specific tools, such as hand shears, scrapers, and special jigs, the sprue is separated from the product by visual inspection and manual operation. However, manual operation is inefficient and cannot guarantee complete removal. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a sprue cutting device that can improve the efficiency of sprue cutting and ensure complete sprue cutting.

[0004] The sprue cutting device according to an embodiment of this application includes: a frame, a positioning mechanism, a pressing mechanism, a cutting mechanism, a material transfer mechanism, and a material unloading mechanism.

[0005] A positioning mechanism, movably mounted on the top of the frame, is used to place injection molded parts with sprue nozzles; A pressing mechanism is located at the top of the frame, above the positioning mechanism, and is used to press the injection molded part of the positioning mechanism. The cutting mechanism is located at the top of the frame, above the positioning mechanism, and is used to cut off the sprue of the injection molded part after pressing. A material transfer mechanism is located at the top of the frame, and a positioning mechanism is located at the top of the material transfer mechanism, used to transport the injection molded part after the sprue has been cut off; The unloading mechanism is located at the top of the frame and on one side of the transfer mechanism, and is used to unload the injection molded parts of the transfer mechanism; The positioning mechanism includes a positioning seat and multiple positioning posts. The positioning seat is located on the top of the material transfer mechanism. The top of the positioning seat has multiple placement grooves. The placement grooves match the shape of one end of the injection molded part. The multiple positioning posts are respectively located in the multiple placement grooves. The injection molded part is cylindrical, and the positioning posts are used to fit the injection molded part.

[0006] The sprue cutting device according to the embodiments of this application has at least the following beneficial effects: when an operator or robot arm places a cylindrical injection molded part with a sprue onto a positioning post, the injection molded part is quickly and accurately placed in a preset fixed position due to the guiding effect of the positioning post and the placement groove on the top of the positioning seat that matches the shape of one end of the injection molded part. This step ensures that each injection molded part has a consistent initial state. Once the injection molded part is in place, the pressing mechanism above the positioning mechanism starts to move downwards and apply pressure to the injection molded part to fix its position. At this time, the cutting mechanism starts to work and cuts the sprue of the injection molded part, which has been firmly fixed. Since the injection molded part itself is completely fixed, the cutting mechanism can precisely act on the sprue connection between the sprue and the injection molded part to achieve a clean and thorough separation. After the cutting is completed, the pressing mechanism and the cutting mechanism reset, releasing the product from fixation. Subsequently, the material transfer mechanism starts to move the entire positioning mechanism on top (along with the injection molded part with the cut sprue) to the next station unloading mechanism for unloading, thus replacing manual operation.

[0024] Reference Figures 1 to 9 The water-cutting nozzle device according to an embodiment of this application includes: 100 racks; The positioning mechanism 200 is movably disposed on the top of the frame 100 for placing the injection molded part 110 with the sprue 112. The pressing mechanism 300 is located on the top of the frame 100, above the positioning mechanism 200, and is used to press the injection molded part 110 of the positioning mechanism 200. The cutting mechanism 400 is located at the top of the frame 100, above the positioning mechanism 200, and is used to cut off the sprue of the injection molded part 110 after pressing. The material transfer mechanism 500 is located on the top of the frame 100, and the positioning mechanism 200 is located on the top of the material transfer mechanism 500, for conveying the injection molded part 110 after the sprue has been cut off. The unloading mechanism 600 is located on the top of the frame 100 and on one side of the transfer mechanism 500. It is used to unload the injection molded part 110 from the transfer mechanism 500. The positioning mechanism 200 includes a positioning seat 210 and multiple positioning posts 211. The positioning seat 210 is located on the top of the material transfer mechanism 500. Multiple placement grooves 213 are provided on the top of the positioning seat 210. The placement grooves 213 match the shape of one end of the injection molded part 110. The multiple positioning posts 211 are respectively located in the multiple placement grooves 213. The injection molded part 110 is cylindrical, and the positioning posts 211 are used to fit the injection molded part 110.

[0025] Understandably, when an operator or robotic arm places the cylindrical injection molded part 110 with the sprue 112 onto the positioning post 211, the injection molded part 110 is quickly and accurately placed in the preset fixed position due to the guiding effect of the positioning post 211 and the placement groove 213 on the top of the positioning seat 210 that matches the shape of one end of the injection molded part 110. This step ensures that each injection molded part 110 has a consistent initial state. After the injection molded part 110 is placed in place, the pressing mechanism 300 above the positioning mechanism 200 starts to move downward and apply pressure to the injection molded part 110 to fix its position. At this time, the cutting mechanism 400 starts to work and cuts the sprue portion 112 of the injection molded part 110 that has been firmly fixed. Since the injection molded part 110 itself is completely fixed, the cutting mechanism 400 can accurately act on the sprue connection portion 111 that connects the sprue portion 112 and the injection molded part 110 to achieve a clean and thorough separation. After the cutting is completed, the pressing mechanism 300 and the cutting mechanism 400 are reset to release the product. Subsequently, the material transfer mechanism 500 starts to move and transfers the entire positioning mechanism 200 at its top (along with the injection molded part 110 with the sprue portion 112 cut) to the next station unloading mechanism 600 for unloading, thereby replacing manual operation.

[0026] Reference Figures 1 to 9 According to some embodiments of this application, the positioning mechanism 200 includes a plurality of positioning top seats 220, which are disposed on the top of the positioning seat 210. The plurality of positioning top seats 220 correspond to a plurality of placement grooves 213 respectively. A positioning cutting groove 221 is provided on the top of the positioning top seat 220. The positioning cutting groove 221 is used to place the sprue connection part 111 between the sprue part 112 and the injection molded part 110.

[0027] Understandably, the operator or robot arm places the cylindrical injection molded part 110 with the sprue onto the positioning post 211 of the positioning mechanism 200. One end of the injection molded part 110 is embedded in the placement groove 213 of the positioning seat 210, thereby being precisely positioned in the horizontal direction. At the same time, the sprue connection part 111 of the injection molded part 110 is placed in the positioning cutting groove 221 opened on the top of the positioning top seat 220. The shape of the positioning cutting groove 221 matches the contour of the sprue connection part 111, so that it is accurately positioned in both the vertical and horizontal directions, so that the cutting mechanism 400 can cut off the sprue connection part 111 in the positioning cutting groove 221.

[0028] It should be noted that the sprue connection 111 is the connection point between the injection molded part 110 and the sprue part 112.

[0029] Reference Figures 1 to 9According to some embodiments of this application, the positioning mechanism 200 includes a plurality of guide heads 212, which are respectively disposed on the top of a plurality of positioning posts 211, and the guide heads 212 are cone-shaped.

[0030] Understandably, when the operator loads the injection molded part 110, it is not necessary to align the injection molded part 110 with the positioning post 211 very precisely. The operator only needs to roughly fit the cylindrical injection molded part 110 onto the guide head 212. Since the guide head 212 is designed as a cone, its inclined surface will automatically guide the inner hole of the injection molded part 110, allowing it to slide in easily and finally be completely fitted onto the positioning post 211, thus achieving preliminary radial positioning.

[0031] Reference Figures 1 to 9 According to some embodiments of this application, the pressing mechanism 300 includes a pressing base frame 310, a pressing moving frame 320, a pressing moving cylinder 321, a pressing lifting cylinder 330, a pressing lifting frame 331, and a pressing plate 332. The pressing base frame 310 is disposed on the top of the frame 100. The pressing moving frame 320 is slidably connected to the top of the pressing base frame 310. The pressing moving cylinder 321 is disposed on one side of the pressing base frame 310 and drives the pressing moving frame 320 to move. The pressing lifting frame 331 is movably disposed on one side of the pressing moving frame 320. The pressing lifting cylinder 330 is disposed on the top of the pressing moving frame 320 and drives the pressing lifting frame 331 to rise and fall. The pressing plate 332 is disposed at the bottom of the pressing moving frame 320.

[0032] Understandably, after the injection molded part 110 is placed, the pressing plate 332 moves and rises and falls through the pressing moving cylinder 321 and the pressing lifting cylinder 330. After the pressing plate 332 reaches the position of the injection molded part 110, the pressing lifting cylinder 330 drives the pressing lifting frame 331 to descend, thereby driving the pressing plate 332 to fix the injection molded part 110, thus preventing the injection molded part 110 from shifting during the cutting process.

[0033] Reference Figures 1 to 9According to some embodiments of this application, the cutting mechanism 400 includes a cutting base frame 410, a cutting moving frame 411, a cutting moving cylinder 412, a cutting connecting seat 420, a cutting cylinder 421, a cutting blade holder 422, and a cutting blade 423. The cutting base frame 410 is disposed on the top of the frame 100, the cutting moving frame 411 is slidably connected to the top of the cutting base frame 410, and the cutting moving cylinder 412 is disposed on one side of the cutting base frame 410, driving the cutting... The moving frame 411 moves, the cutting connecting seat 420 is located on one side of the cutting moving frame 411, the cutting blade seat 422 is movably connected to the bottom of the cutting connecting seat 420, the cutting cylinder 421 is located on the top of the cutting connecting seat 420, the cutting cylinder 421 drives the cutting blade seat 422 to rise and fall, there are multiple cutting blades 423, the multiple cutting blades 423 are respectively located at the bottom of the cutting blade seat 422, the multiple cutting blades 423 are respectively facing the positioning cutting grooves 221 of the multiple positioning top seats 220.

[0034] Understandably, the cutting cylinder 412 drives the cutting frame 411 to move, thereby moving multiple cutting blades 423 toward the cutting position. After reaching the predetermined position, the cutting cylinder 421 drives the cutting blade holder 422 to move vertically downward along the cutting connecting seat 420. The multiple cutting blades 423 installed at the bottom of the cutting blade holder 422 move downward synchronously. Since the multiple cutting blades 423 are respectively facing the positioning cutting grooves 221 of the multiple positioning top seats 220, it is convenient to cut the water inlet connection 111 in the positioning cutting groove 221.

[0035] Reference Figures 1 to 9 According to some embodiments of this application, the unloading mechanism 600 includes an unloading bracket 610, an unloading moving device 620, an unloading moving frame 621, an unloading cylinder 630, an unloading lifting frame 640, an unloading connecting plate 641, and an unloading pneumatic finger 650.

The unloading moving device 620 drives the unloading moving frame 621 to move, thereby unloading materials. The lifting frame 640 is slidably connected to one side of the unloading moving frame 621. The unloading cylinder 630 is located on the top of the unloading moving frame 621. The unloading cylinder 630 drives the unloading lifting frame 640 to rise and fall. The unloading connecting plate 641 is located at the bottom of the unloading lifting frame 640. There are multiple unloading pneumatic fingers 650. The multiple unloading pneumatic fingers 650 are respectively located at the bottom of the unloading connecting plate 641. The bottom of the unloading pneumatic fingers 650 is provided with two unloading clamping fingers 651. The unloading pneumatic fingers 650 drive the two unloading clamping fingers 651 to open and close.

[0036] Understandably, after the injection molded part 110 is cut off, the material transfer mechanism 500 transfers the injection molded part 110 carrying the cut-out gate to the unloading mechanism 600. The unloading moving device 620 drives the unloading moving frame 621 to move, so that all the unloading pneumatic fingers 650 move together above the injection molded part 110. The unloading cylinder 630 is activated, driving the unloading lifting frame 640 to move vertically downward, causing the unloading connecting plate 641 and multiple unloading pneumatic fingers 650 to descend, so that the unloading clamping fingers 651 insert into the interior of the adjacent injection molded part 110. The unloading pneumatic fingers 650 drive the two unloading clamping fingers 651 at their bottom to unfold, thereby accurately and reliably clamping the interior of the cylindrical injection molded part 110 for unloading.

[0037] Reference Figures 1 to 9 According to some embodiments of this application, the unloading mechanism 600 includes a plurality of feeding seats 660, which are located on the top of the frame 100. The unloading connecting plate 641 is located above the feeding seats 660, and the top of the feeding seats 660 is provided with a plurality of feeding ports 661.

[0038] Understandably, when the feed clamp 651 holds the inside of the injection molded part 110, the feed moving device 620 drives the injection molded part 110 to the multiple feed ports 661 of the feed seat 660.

[0039] Reference Figures 1 to 9 According to some embodiments of this application, the feeding mechanism 600 includes a plurality of connecting pipes 663 and a plurality of collection boxes 664.

One end of the connecting pipe 663 is connected to the adjacent feed port 661, and the other end of the connecting pipe 663 is connected to the interior of the adjacent collection box 664.

[0040] Understandably, when the injection molded part 110 enters the feed port 661, the injection molded part 110 is collected into the collection box 664 along the connecting pipe 663, which facilitates the collection of multiple processed injection molded parts 110; at the same time, the top of the feed seat 660 is located on the top of the frame 100, making the top space of the frame 100 relatively compact; and the internal space of the frame 100 is increased, so that the collection box 664 can be designed to be larger, so as to collect more injection molded parts 110.

[0042] Understandably, when the sprue connection 111 is cut off, the sprue part 112 connected to the sprue connection 111 is guided into the waste chute 230 to slide out, thereby preventing the sprue part 112 from accumulating on the positioning mechanism 200.

The waste box 250 is located on the bottom surface inside the installation cavity 241, and one end of the waste pipe 240 is connected to the inside of the waste box 250.

[0044] Understandably, when the sprue section 112 is guided into the waste chute 230 for discharge, the sprue section 112 slides into the waste bin 250 through the waste pipe 240 for collection, thereby facilitating the unified treatment of the sprue section 112.
